Having been accompanied by many musicians in many music genres, on various instruments over the years, Some pounded so loudly on pianos as well as guitars that I could hardly hear myself sing--and I was trained to sing opera above an entire orchestra! I have found precious few who are truly talented accompanists. I often accompany music students on piano or guitar, etc, but it is a chore I do not look forward to, as I am not so good at it myself! The best accompanist is one who can truly anticipate the thoughts, the breathing, ie the interpretation by the soloist of a given work of music. The good accompanist is one who plays so that we may float upon and soar above their music. My old Voice teacher taught me that the greatest compliment you may ever give an accompanist is "Why, I didn't even know you were there." Think about this the next time you accompany another musician!
